of children. The principal object of the in vention is to provide an improved arrangement of pictures and reading mattei' in combination with a device for projecting the pictures onto a wall or screen successively.

`A further object is Ito provide an improved arrangement of pictures and reading matter in. a printed book adapted for projecting purposes. A-further import-ant object is to provide a projecting device which may be placed over a picture occupying a horizontal position to project the picture onto a vertical wall'or screen. A further object is to provide a projecting device having improved means for adjusting `the position of the source of light and for focusing the lens through which the pictures are projected.

These and other objects and advantages of the invention will be more clearly apparent from the'following specification, taken with the accompanying drawings in which one embodiment is illustrated. In the drawings Fig. l shows a plan view of an open book embodying the features of the present invention with the picture projecting apparatus in position thereon: Fig. 2 shows a front end elevation of the picture proje ting deyice; Fig. 3 shows a longitudinal projec tion on the line 3 3 of Fig. 2; Fig. 4 shows a rear end elevation of the device and Fig. 5 shows a bottom plan view'of the device.

As illustrated in Fig. 1 the improved book comprises a plurality ofpages mounted in a binding 11 in the usual manner. Each page is provided with two horizontal rows 12 and 13 of pictures arranged along the upper and lower edges of the page, respectively, and another row of pictures 14 arranged between the horizontal rows at the outer endof the page. The intermediate part of the page is covered with printed matter 15 which may be'descriptive of the pictures around, the border of the page so that Athe book may be employed for the education and amusement of children. The lpictures are all arranged in upright position as viewed inthe drawing and the picture projecting device is adapted to be passed lover tliggpictures in Asuccession as the printed composition is read, thereby projecting the pictures onto a wall or screen andillustratmg the subject lmatter of the composition.

The yprojecting device 20 comprises a' sheet metal case or housing 2l having side walls 22, a lower wall 23, a curved upper wall 24 andan inclined rear wall 25. An opening 26 is provided between the rear end of the lower wall 23 and the lower extremity of the wall 25 and this opening is adapted to register with any one of the pictures on the rlnted page. The picturewhich is framed y the opening 26 is illuminated by an electric lamp 28 which is mounted in the upper 'chamber 29 of the housingbeneath the curved wall 24, whichmay conform substantially to the outer curvature of the lamp bulb. The walls of the casing form a circular opening 30 at the rear end of the cham `ber 2,9 and this opening is adapted to receive a cap member 31 in which the lamp socket 32 is mounted. The lamp socket is connected to electric wires 33 and is eccentrically located with respect to the axis of the cap 31 so that the cap may be 'rotated in order to adjust the vertical position of the lamp 28 with respect to the opening 26. For the purpose of Ventilating the chamber occupied by the lamp, a series of a ertures 35 are provided inthe upper wal 24 and a hood 36, open at its rear end, is mounted Vover these apertures to prevent the entrance of dust and moisture.

The picture which occupies the opening 26 and is thus' illuminated by the lamp 38 is reflected by a mirror 28 mounted on the rear wall 25, preferably at an angle of about to the horlzontal, and the reflected image is projected by this mirror .through the cylindrical outlet 39 formed in the forward wall of the casing and having a cylindrical barrel 40 mounted therein and carr ing a magnifying lens 4.1 at its forward en The barrel 40 has a frictional engagement with the walls of the outlet 39 which is suiliciently tight to hold the lens in adjusted position while permitting longitudinal movement thereof for bringing about the proper focus of the lens with any selected picture land -any appropriate spaced relation ofthe pro- `the picture projecting device the inner surface of the side walls 22 and of the bottom wall 23 are preferably covered with a dull black coating of paint or other suitable material, but the inner .surface of the upper inc curved wall '24 should preferably be a pol- *i ished bright surface iny order to reflect the light, which passes upwardly from the lamp bulb.

Although I have shown and described one 'form of the invention for purposes of illustration it will be understood that it may be constructed in various other forms ,without departing from the scope of the appended claims.

1. A picture projecting device comprising a casing having an opening in its bottom Wall and a second opening in its rear wall, a circular cap member rotatively mounted in said second opening, a lamp carried -by said cap member with its axis located eccentrically with the axis of said cap member and a inirrormounted in 'said casing over said first named opening, said casing having an outlet through which the image in said mirror is adapted to be projected.

2. A- picture projecting device comprising a casing having an opening in its bottom wall and afsecond opening in its rear wall.. a circulancap member rotatively mounted in #a casingl cated over a picture,

a mirror mounted in said casing over said iist named opening,said casing having an outlet through which the image in said mirror is adapted to be projected, and a lens adjustably mounted in said outlet.

- 3. -A picture projecting device comprising having a ilat bottom wall provided with an opening therein adapted to be loc said casing having an inclined rear wall, a mirror mounted on said rear wall over said opening in an inclined position, a barrel adjustably. mounted in the front side of said casing 1n front of said mirror, a lens carried in 4said barrel, said casing having a light chamber mounted in the upper part thereof, a lamp mountedV in said chamber, fand a cap rotatably mounted in the rear wall 'of said casing to support said lamp, trically located with respect to the axis of rotation of said cap-member.
